Test drives

I've done a few test drives now. Some tens of kilometres here in the neighbourhood. It has been some trouble getting the carburetor settings right but I think I am close to it now. In some drives the engine didn't run well around half throttle. Based on some post in the net I thought this could be due to a lean mixture so I set the needle from the middle groove to the lowest one. Now it runs pretty well. I haven't checked the spark plug after the last drive yet. But hopefully it looks good. The spark plug in the engine is now a little hotter than the one recommended in the manual. I don't know if this has been a conscious decision by a previous owner or by accident. I'll check the spark plug before my next ride but I think I will change it back to the recommended one.

This post has been pretty good on carburetor settings, www.cycleworld.com/story/bikes/kevin-cameron-explains-how-to-tune-carburetors/.

I also found this YouTube video from Rolling Wrench really good www.youtube.com/watch?v=rCo6dJAxi64.
